Zirr bin Hubaish says: During the caliphate of Sayyiduna Uthman bin Affan (may Allah be pleased with him), I set out on a journey. The thing that motivated me for this journey was the meeting with Sayyiduna Ubayy bin Ka'b and other companions. So I met Sayyiduna Safwan bin Assal (may Allah be pleased with him) and said: Did you see the Messenger of Allah (peace and blessings be upon him)? He said: Yes, indeed, I even participated in twelve battles with him (peace and blessings be upon him).
